Science and technology are the primary productive forces. With the development of intelligent control and health lighting technology in China, the cabin construction of China‘s space station is also progressing. Health lighting and smart home are widely used to provide more comfortable space environment for astronauts.

        According to the China Manned Space Engineering Office, on June 17, 2021 Beijing time, the shenzhou-12 manned spacecraft was successfully launched at Jiuquan Satellite Launch Center, successfully sending three astronauts, Nie Haisheng, Liu Boming and Tang Hongbo, into space. This time, the astronauts stayed in the space station for three months. In order to improve the "comfort" of the astronauts‘ space life, the activity space in the cabin was increased from 15 cubic meters of Tiangong-1 to 110 cubic meters of the whole station, which is almost from the "tube room" to the "big flat floor".

        In China space station, designers have prepared a hand-held terminal for each astronaut. Astronauts can adjust the lighting environment in the cabin, sleep mode, work mode and movement mode through app according to their personal needs. The lighting environment of Tiangong space station simulates many natural states such as sunrise, noon, dusk and night, To the greatest extent for the astronauts in the sky to create an atmosphere of human life. Different cabin lights can adjust the mood of astronauts and avoid discomfort caused by monotonous environment for a long time. This is the combination of health lighting and smart home. It is reported that in order to achieve the ideal healthy lighting effect, designers have carried out many experiences, repeatedly verified and adjusted the lighting, and used the most advanced intelligent control means to make the astronauts who stay in space for a long time have a comfortable life experience as much as possible.
